Some Things To Ponder On – Intro To Programming 101

A lot of people are getting into programming these days because they love computers, coding and want to make a career in the IT industry. A career in the tech industry is diversified and rewarding, and thus, a good programmer can quickly move up the corporate ladder. This post is helpful for any novice who is interested in coding. Adapt your style How to learn a new language? Should I read the documentation? Should I join a Bootcamp? Should I watch video lectures? Should I ..?? These are the most common questions beginners face, and different people give different answers. You might ask “What should I do?” or “Whom should I listen to?”. Well, the simple answer is to try different ways of learning and choose the one that suits your style and stick to it. The way you learn might or might not vary from language to language but irrespective of that, it will be your unique way of learning. This will give you accelerated growth in the long run. Learn by doing! Reading books, watching video tutorials and not writing a single line of code can be the most ineffective way to learn a new language. And cramming is no better! There are various resources online which follow the “learn by doing” concept. You can also learn by solving programming challenges in online forums or, you can try to build an app or website from scratch and learn the language on the fly! Write neat code! Generally, most of the beginners, especially those who are self-taught tend to write messy code, that is, without proper formatting and commenting. There is no foresight nor a designed plan or algorithm in mind. After getting comfortable with at least one language, while working on a project, one should first develop the algorithm before starting the implementation and make sure that the language is utilised to its maximum efficiency. Most beginners tend to ignore the naming conventions, which is a very serious problem. It is important to give proper names to functions, it not only makes your code understandable for other programmers but also helps a lot during debugging and testing phases. Also, many times, functions can become huge unintentionally which complicates the code drastically. Recursion should be used wherever applicable. Languages, frameworks and platforms When starting to learn web programming, you hear lots of new terms. You might hear people talk about platforms and frameworks. The answer to which framework you choose would depend on the answer to the questions like “Which platform should I use? PHP? JAVA? .NET?” A platform is an underlying service provider. A Framework is a set of predefined functions and classes which a developer uses for faster development. According to Wikipedia, “A web framework (WF) is a software framework that is designed to support the development of web applications including web services, web resources and web APIs. Web frameworks aim to alleviate the overhead associated with common activities performed in web development. “ It is very important to understand the need and use of many general purpose frameworks. For example, Django and Ruby on Rails are popular frameworks for the server side whereas AngularJS is widely used in the client-side. Apart from these, there are different types of languages; HTML is a Markup language and CSS is a styling language. Javascript is used widely for frontend development. “Is Javascript the same as Java?” is a very common question as well, it’s like comparing oranges to apples, they are very different. So before going into web development it would be better to understand these concepts in detail for the long run. Learn to debug! Developers often tend to stare at their code for hours trying to find errors in logic or syntax but good developers usually get the desired code quickly by using debuggers properly. Not using a debugger can be as bad slow you down. When you use a debugger, you get additional information on what might have gone wrong other than your basic thought process. It’s like thinking out of the box! I am not biased about code editors( Nah, Sublime Text is the best!) Use your search engine! It doesn’t matter whether you use Google, Yahoo or Bing as your search engine but whatever it is, try searching your doubts as much as possible. It is very easy to debug errors, just copy the error text and there is a 9/10 chance that someone might have already asked the same question in popular forums like Stackoverflow. There is nothing wrong in searching the web for language syntax, developers all over the world refer to the code documentation often, in fact, it is excellent practice to be up to date! Wrapping up Never forget that everyone’s different. Choose the languages you like and work on projects that excite you. Do not write messy code and learn by coding. The more you code, the better coder you will become. Understand concepts thoroughly before jumping into detail. Make the best use of IDE’s, debugging tools and your search engine. Remember: while( !

Some Things To Ponder On – Intro To Programming 101

A lot of people are getting into programming these days because they love computers, coding and want to make a career in the IT industry. A career in the tech industry is diversified and rewarding, and thus, a good programmer can quickly move up the corporate ladder. This post is helpful for any novice who is interested in coding.

Adapt your style

How to learn a new language? Should I read the documentation? Should I join a Bootcamp? Should I watch video lectures? Should I ..??
These are the most common questions beginners face, and different people give different answers. You might ask “What should I do?” or “Whom should I listen to?”. Well, the simple answer is to try different ways of learning and choose the one that suits your style and stick to it. The way you learn might or might not vary from language to language but irrespective of that, it will be your unique way of learning. This will give you accelerated growth in the long run.

Learn by doing!

Reading books, watching video tutorials and not writing a single line of code can be the most ineffective way to learn a new language. And cramming is no better!
There are various resources online which follow the “learn by doing” concept. You can also learn by solving programming challenges in online forums or, you can try to build an app or website from scratch and learn the language on the fly!

Write neat code!

Generally, most of the beginners, especially those who are self-taught tend to write messy code, that is, without proper formatting and commenting. There is no foresight nor a designed plan or algorithm in mind. After getting comfortable with at least one language, while working on a project, one should first develop the algorithm before starting the implementation and make sure that the language is utilised to its maximum efficiency.

Most beginners tend to ignore the naming conventions, which is a very serious problem. It is important to give proper names to functions, it not only makes your code understandable for other programmers but also helps a lot during debugging and testing phases. Also, many times, functions can become huge unintentionally which complicates the code drastically. Recursion should be used wherever applicable.

Languages, frameworks and platforms

When starting to learn web programming, you hear lots of new terms. You might hear people talk about platforms and frameworks. The answer to which framework you choose would depend on the answer to the questions like “Which platform should I use? PHP? JAVA? .NET?”
A platform is an underlying service provider. A Framework is a set of predefined functions and classes which a developer uses for faster development. According to Wikipedia, “A web framework (WF) is a software framework that is designed to support the development of web applications including web services, web resources and web APIs. Web frameworks aim to alleviate the overhead associated with common activities performed in web development. “

It is very important to understand the need and use of many general purpose frameworks. For example, Django and Ruby on Rails are popular frameworks for the server side whereas AngularJS is widely used in the client-side. Apart from these, there are different types of languages; HTML is a Markup language and CSS is a styling language. Javascript is used widely for frontend development. “Is Javascript the same as Java?” is a very common question as well, it’s like comparing oranges to apples, they are very different. So before going into web development it would be better to understand these concepts in detail for the long run.

Learn to debug!

Developers often tend to stare at their code for hours trying to find errors in logic or syntax but good developers usually get the desired code quickly by using debuggers properly. Not using a debugger can be as bad slow you down. When you use a debugger, you get additional information on what might have gone wrong other than your basic thought process.

Use your search engine!

It doesn’t matter whether you use Google, Yahoo or Bing as your search engine but whatever it is, try searching your doubts as much as possible. It is very easy to debug errors, just copy the error text and there is a 9/10 chance that someone might have already asked the same question in popular forums like Stackoverflow.

Wrapping up

Never forget that everyone’s different. Choose the languages you like and work on projects that excite you. Do not write messy code and learn by coding. The more you code, the better coder you will become. Understand concepts thoroughly before jumping into detail. Make the best use of IDE’s, debugging tools and your search engine.

Top 10 Python IDEs and Code Editors

Over the years, Python language has evolved enormously with the contribution of developers. Python is one of the most popular programming languages. It was designed primarily for server-side web development, software development, evaluation, scripting and artificial intelligence. For this feature Python encloses certain code editors and IDEs that are used for software development say, Python itself. If you are new to programming, learning Python is highly recommended as it is fast, efficient and easy to learn. Python interpreters are available on various operating systems such as Windows, Linux, Mac OS. This article provides a look into code editors and IDEs along with their features, pros and cons and talks about which are the best suited for writing Python codes. But first let us see what are code editors and IDEs. What is a Code Editor? A code editor is built for editing and modifying source code. A standalone text editor is used for writing and editing computer programs. Excellent ones can execute code as well as control a debugger as well as interact with source control systems. Compared to an IDE, a good dedicated code editor is usually smaller and quicker, but is less functional. Typically they are optimized for programming languages. One major feature of a text editor is that they are designed to modify various files and work with whatever language or framework you choose. What is IDE? IDE (Integrated Development Environment) understands the code significantly better than a text editor. It is a program exclusively built for software development. It is designed with a set of tools that all work together:  Text editor  Compiler Build automation Debugging Libraries, and many more to speed up the work.  These tools integrate: An editor designed to frame codes with text formatting, auto-completionetc., build, execution, debugging tools, file management and source and version control. It reduces manual efforts and combines all the equipment in a typical framework. IDE comes with heavy files. Hence, the downloads and installation is quite tedious. IDE requires expertise along with a lot of patience.  How does an IDE and Code editor differ from each other? An IDE is distinctive from code editors in the following ways: Integrated build process:The user does not have to write his own scripts to build apps in an IDE.  File management: IDE has an integrated file management system and deployment tool. It provides support to other framework as well. On the other hand, a Text editor is a simple editor where source code can be edited and it has no other formatting or compiling options. Development Environment: An IDE is mainly used for development purposes as it provides comparatively better features than a text editor. It allows you to write, compile and debug the entire script.  Syntax Highlighting:The editor displays the text message and puts the source code in different colours to improve its readability. Even error messages are displayed in different colours so that the user understands where he has written the wrong code.  Auto completion:It identifies and inserts a common code for the user instantly. This feature acts as an assistance for the programmer. The code suggestion automatically gets displayed.  Debugger: This tool helps the programmer to test and debug the source code of the main program.  Although IDEs have far better features than a Text editor one major significance of Text editor is that it allows modifying all types of files rather than specifying any definite language or types. Features For a good software development, we need code editors and IDEs which help the developer to automate the process of editing, compiling, testing, debugging and much more. Some of the features of these editors are listed below: Good user interface: They allow users to interact and run programs easily. Incredibly fast: Although these IDEs need to import heavy libraries, compile and debug, they offer fast compilation and run time.  Syntax stylizing: Codes are colorized automatically and syntax is highlighted.    Debugging tool: Itruns the code, set breakpoints, examine the variables. Provides good language syntax: IDEs usually work on a specific language but the others are designed for multi-language support. Code editors are designed with multi-language support.  Good source and version control environment: IDEs come with source control feature to keep a track of changes made in source code and other text files during the development of any software. Intelligent code completion:This feature speeds up the coding process by automatically suggesting for incomplete codes. It reduces typos and other common mistakes. Why do we need a good coding environment? For a good software development one seeks a better coding environment. Although features vary from app to app, a definite set of features is required for one. There are many other things involved such as source code control, extension tools, language support etc. Listed below are the core features which make a good coding environment : Retrieve files: All the codes written in an IDE get saved. Also, the programmer can retrieve his code file at the same state where the work is left off. Run within the environment: It should be able to compile and run within the environment where the codes are written. No external file shall be needed to be downloaded for the execution of the programs.  Good Debugging Tool: An IDE or editor should be able to diagnose and  troubleshoot the programmer’s works and highlight the lines with errors if any. A pop-up window should display the error message. This way the programmer can keep a track of his errands and diagnose them.   Automatic formatting tool: Indentation is done automatically as soon as the programmer moves onto the next line. It keeps the code clean and readable. Quick highlighting: keywords, variables and symbols are highlighted. This feature keeps the code clean and easy to understand. Also, pops up the variables making them easy to spot. This makes it a whole lot easier to pick out portions of code than simply looking at a wall of undifferentiated text. Some of the IDEs and code editors There are various Python IDEs and text editors. Some of the IDEs and text editors along with their features and pros and cons are mentioned below: IDLEKey Features: It is an open source IDE entirely written in Python. It is mainly supported by WINDOWS, LINUX, MAC OS etc.. IDLE is a decent IDE for learning because it is lightweight and quite simple to use.

IDE being a program dedicated to software development has made it easier for developers to build, execute, and debug their codes. Code editors can only be used for editing codes whereas an IDE is a feature rich editor which has inbuilt text editor, compiler, debugging tool and libraries. Different IDEs and code editors are detailed in this article along with their merits and demerits. Some are suitable for beginners because of their lightweight nature and simplicity like IDLE, Thonny whereas experts require advance featured ones for building software.  For learning purposes say data science, machine learning Jupyter and Google Colaboratory are strongly recommended. Again there are large scale enterprises who prefer PyCharm, Atom, Sublime Text for software development. On the other hand, small scale enterprises prefer Spyder, Pydev, IDLE and Visual Studio. Hence,the type of IDE or code editor that should be used completely depends upon the requirement of the programmer .

Scala Vs Kotlin

Ever-changing requirements in coding have always been happening, ones that cause programmers to change their minds about using the appropriate programming language and tools to code. Java has been there for a long time, a really long time, 24 years ago. It is relatively easy to use, write, compile, debug, and learn than other programming languages. However, its certain inhibitions like slow performance, unavailability of any support for low-level programming, possessing poor features in GUI 4, and having no control over garbage collection is putting Java developers in a dilemma on choosing an alternative to Java, such as JetBrains’ programming language, Kotlin, presently an officially supported language for Android development or Scala, an all-purpose programming language supporting functional programming and a strong static type system. Today, we will discuss how developers can decide to choose Scala or Kotlin as an alternative to Java. We will briefly talk about Scala and Kotlin separately and talk about their application before moving forward to looking at the differences, advantages, and disadvantages of both and finally have you decide which one of these two suits your requirements. User’s requirement Before we begin, here is a question for the readers, ‘What are you looking for in the next programming language that you will use?’ It is an obvious question because the programming purposes drive the actual basis and need of developing a language. Do you need a language that strives to better Java or use a language that lets you do things that aren’t possible in Java? If it is the first reason, then Scala might be the best one for you, otherwise, it is a simplified programming language like Kotlin. Now let us first briefly discuss Scala and Kotlin individually. ScalaDeveloped by Martin Odersky, the first version of Scala was launched in the year 2003 and is a classic example of a  general-purpose, object-oriented computer language, offering a wide range of functional programming language features and a strong static type system. Inspired from Java itself, Scala, as the name suggests, is highly scalable and this very feature sets Scala apart from other programming languages. When we say that Scala is inspired from Java, that means developers can code Scala in the same way they do for Java. Additionally, Scala makes it possible to use numerous Java and libraries within itself as well. It is designed to be able to use an elegant, concise and type-safe method to express common programming patterns. Scala is a very popular programming language amongst developers and rising up its ranks in the world of technology. Although Scala comes with a number of plus points, there are some which make it a bit ineffective. Here are the strengths and weaknesses of Scala. Strengths: Full Support for Pattern Matching, Macros, and Higher-Kinded Types Has a very flexible code syntax Gets a bigger Community Support Enables overloading operators Weaknesses: Slow in compilation Challenging Binary Compilation Not so proficient in the Management of Null SafetyKotlin Developed by JetBrains, Kotlin was released on February 2012 as an open-source language. Until now, there have been two released versions with the latest one being Kotlin 1.2, the most stable version that was released on November 28, 2017. Since Kotlin is extremely compatible with Java 6 the latest version of Java on Android, it has gained critical acclaim on Android worldwide and additionally, it offers various key features that are prepared only for Java 8 and not even Java 6 developers have access to that. Kotlin provides seamless and flawless interoperability with Java. That means, developers can easily call Java codes from Kotlin and same goes the other way around. The built-in null safety feature avoids showing the NullPointerException (NPE) that makes developing android apps easy and joyful, something every android programmer wants. Below mentioned are the key pointers on the strengths and weaknesses of Kotlin. Strengths Takes a Functional Programming Approach and Object-Oriented Programming style(OOP) Style  Has Higher-Order Functions Short, Neat, and Verbose-Free Expression  Supported by JetBrains and Google. Weaknesses: More limited Pattern Matching Additional Runtime Size Initial Readability of Code Shortage of Official Support Smaller Support Community. Ease of learning: Scala vs Kotlin Scala is a powerful programming language packed with superior features and possesses a flexible syntax. It is not an easy language to learn and is a nightmare for newcomers. Kotlin, on the other hand, has been reported to have been an easy-to-learn language for many Java developers as getting started with Kotlin is relatively easy and so is writing codes. Even though it is a comparatively easier language to learn and code with, Kotlin lacks the solid set of features that is common in Scala. It might take less time to learn a programming language, but the most important thing to look for is a comprehensive array of features. Scala, even though a very difficult language to learn, is cherished by the developers as it lets them do things that cannot be done in Kotlin Here are the major differences between Scala and Kotlin: ScalaKotlinType inferenceEfficientImmutabilityExtension FunctionsSingleton objectMassive InteroperabilityConcurrency controlLessens Crashes at RuntimeString interpolationSmart Cast FunctionHigher-order functionSafe and ReliableCase classes and Pattern matching Lazy computationLow adoption costRich collection setMaking the appropriate choice of languageNow, whether you may like a programming language or not, if that very language helps you get the best out of your job, then you will have to live with it. These are the facts about getting the best results. The outcome is the main factor in you deciding the appropriate language for your job. Kotlin is the only option for Android development as Android doesn’t use JVM, so any old JVM-compatible language will not work in Android. Kotlin has it all what it takes to compile, debug, and run the software on Android because of which it is in-built into Android Studio. However, Kotlin is not so usable outside Android development. If you are one of the developers who like working with Eclipse for your IDE, then Scala IDE is better than the Kotlin Plugin even if you can make Eclipse work with both the languages with limitations. Scala IDE is more advanced than the Kotlin plugin and is easier to set up. Some developers found it quite difficult to make the Kotlin plugin work. This case is quite the same with NetBeans. Kotlin is still getting there but is already popular amongst Java developers as it offers an easier transition than Scala. Kotlin is still maturing, but many Java people find adopting it is an easier transition than Scala is.  Scala, however, is for developers who are focused more on discovering new ideas while Kotlin is for those who want to get results. Kotlin stresses fast compilation but is more restrictive while Scala gives a lot of flexibility. Go for Scala if you breathe functional programming! It has more appropriate features for this type of programming than Kotlin does. Scala supports currying and partial application, the methods of breaking down functions requiring multiple arguments offering more flexibility. Go for the one that is the most appropriate one for your work, style of working and what you are aiming at. Think before you leap. The Outcome At the end of the day, all that matters is what you want to use the language for. While Scala goes well for the projects that require a combination of functional, OOP style programming languages, and where programmers need to handle lots of data or complex modelling, Kotlin becomes the best choice when you want something less frustrating than Java while developing apps because using Kotlin makes app development less cumbersome and a great thing to work on. It is just like a better-looking version of Java with less lengthy codes.

Xcode vs Swift

Xcode and Swift are two different products developed by Apple for macOS, iOS, iPadOS, watchOS, and tvOS. While Xcode is an integrated development environment (IDE) for macOS containing a suite of software development tools to develop software for macOS, iOS, iPadOS, watchOS, and tvOS, Swift is a general-purpose, multi-paradigm, compiled programming language developed iOS, macOS, watchOS, tvOS, Linux, and z/OS. So it is clear that they can not be compared with each other. On the contrary, Swift is compatible with Xcode as Swift v 5.1, the default version of Swift is included in Xcode v 11. In this article, we will go through what Xcode and Swift are in general and cover their features strengths and weaknesses followed by how Swift is compatible with Xcode. XcodeIt was first released in 2003 as version 1 with the latest stable one being version 10.2.1 released on 17 April 2019. It can be downloaded from the Mac App Store and is free to use for macOS Mojave users. Registered developers may download the preview releases and previous versions of the suite using via the Apple Developer website.  Overview of the major featuresSupport: Programming languages such as C, C++, Objective-C, Objective-C++, Java, AppleScript, Python, Ruby, ResEdit (Rez), and Swift are supported by Xcode with source code along with support for a variety of programming models including Cocoa, Carbo, and Java. Not only that, there is additional support via third parties for GNU Pascal, Free Pascal, Ada, C#, Perl, and D Capability: Xcode can build fat binary files that include the code for various architectures in the Mach-O executable format. Known as universal binary files, these allow the application to run on both PowerPC and Intel-based (x86) platforms including both 32-bit and 64-bit codes Compiling and debugging: Xcode uses the iOS SDK to compile and debug applications for iOS that run on ARM architecture processors GUI tool: Xcode comprises of the GUI tool, Instruments that runs dynamic tracing framework on the top of DTrace, a dynamic tracing framework designed by Sun Microsystems and released as a part of OpenSolaris. Advantages and disadvantages of Xcode: Xcode is designed by Apple and will only work with Apple operating systems: macOS, iOS, iPadOS, watchOS, and tvOS. Since its release in 2003, Xcode has made significant improvements and the latest version, Xcode 10.2.1 has all the features that are needed to perform continuous integration. Let us have a look at the pros of using Xcode: Equipped with a well designed and easy to use UI creator Excellent for code completion Using Xcode, a developer can learn profiling and heap analysis in a natural way Xcode’s simulator lets you easily test your app while you build it in an environment that simulates your iPhone The app store has a wide range of audience who are willing to pay for apps. Now, the cons: Clunky and outdated Objective C makes it more frustrating if you are habituated to use a modern language No support for tabbed work environments makes it difficult to work with multiple windows Hardly any information can be found online to solve problems due to a previous Apple NDA on Xcode development It is a complicated process to export your app onto a device Will only work with Apple operating systems The App Store approval process can be annoyingly lengthy.SwiftSwift was launched at Apple's 2014 Worldwide Developers Conference as a general-purpose, multi-paradigm, compiled programming language for iOS, macOS, watchOS, tvOS, Linux, and z/OS Being a new entry these operating systems, Swift accelerates on the best parts of C and Objective C without being held back by its compatibility. It utilises safe patterns for programming, adding more features to it, thus making programming easier and more flexible. By developing their existing debugger, compiler and framework infrastructure, it took quite some time to create the base for Swift. Furthermore, Automatic Reference Counting was used to simplify the memory management part. The framework stack which was once built upon a solid framework of Cocoa and Foundation has undergone significant changes and is now completely regulated and refurbished. Developers who have worked with Objective-C do find Swift quite similar. Objective-C’s dynamic object model and its comprehensively named parameters provide a lot of control to Swift.  Developers can use Swift to have access to the existing Cocoa framework in addition to the mix and match interoperability with an objective C code. Swift uses this common rule to offer multiple new features in combination with object-oriented and procedural portions of the language. The idea is to create the best possible language for a wide range of uses, varying from desktop and mobile apps, systems programming, and scaling up to cloud services. The designing of Swift was done to make sure that developers find it easy to maintain and write correct programs. Coding done in Xcode is safe, fast and expressive. Swift offers a host of features that give developers the control needed to make the code easy to read and write. Furthermore, Apple made Swift to be easily understandable to help developers avoid making mistakes while coding and make the code look organised, along with the modules that give namespaces and eliminate headers. Since Swift uses some features present in other languages, one of them being named parameters written with clean syntax that makes the APIs much easier to maintain and read. Here are some of the additional features of Swift: Multiple return values and Tuples Generics Short and quick iterations over a collection or range Structs that support extensions, methods and protocols Functional programming patterns Advanced control flow Powerful error handling. These features are systematically designed to make them work together resulting in creating a powerful but fun-to-use language. Advantages and disadvantages of Swift: Pros of using the Swift Programming language: Easy to read and maintain: The Swift program codes are based on natural English as it has borrowed syntaxes from other programming languages. This makes the language more expressive Scalable: Users can add more features to Swift, making it a scalable programming language. In the future, Swift is what Apple is relying on and not Objective C Concise: Swift does not include long lines of code and that favours the developers who want a concise syntax, thus increasing the development and testing rate of the program Safety and improved performance: It is almost 40% better than the Objective-C when speed and performance are taken into consideration as it is easy to tackle the bugs which lead to safer programming Cross-device support: This language is capable of handling a wide range of Apple platforms such as iOS, iOS X, macOS, tvOS, and watchOS. Automatic Memory Management: This feature present in Swift prevents memory leaks and helps in optimizing the application’s performance that is done by using Automatic Reference Counting. Cons of Swift: Compatibility issues: The updated versions Swift is found to a bit unstable with the newer versions of Apple leading to a few issues. Switching to a newer version of Swift is the fix but that is costly Speed Issues: This is relevant to the earlier versions of the Swift programming language Less in number: The number of Swift developers is limited as Swift is a new programming language Delay in uploading apps: Developers will be facing delays over their apps written in Swift to be uploaded to the App Store only after iOS 8 and Xcode 6 are released. The estimated time for release is reported to be September-October, 2014. Conclusion So as we discussed both Xcode and Swift, it is clear that they cannot be compared to each other. In fact, they both complement each other to deliver impressive results without any headaches. Apple relies on both quite a lot and it is certain to have Swift and Xcode the perfect combination of a robust application and a user-friendly programming language.
